EYEGLASSES.

SPECIFICATION forming part of Letters Patent No. 722,521, dated March 10, 1903. Application filed May 6, 1902. Serial No. 106,157. (No modelJ To all whom it nuty concern:

Be it known that I, EMIL L. LEMBKE, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in

5 the county and State of New York, have invented new and useful Improvements in Eyeglasses, of which the following is a full, clear, and exact description.

The object of the invention is to provide certain new and useful improvements in eyeglasses, whereby the appearance of the eyeglasses is heightened and the screws for fastening the spring and the nose-clamps to the posts are locked against accidental unscrewing and the said screws are protected from moisture to prevent corrosion and cannot possibly come in contact with the wearers skin and bruise the, same, as is so frequently the case with eyeglasses as heretofore constructed.

The invention consists of novel features and parts and combinations of the same, as will be more full described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a front elevation of a pair of eyeglasses provided with the improvement. Fig. 2 is an enlarged front elevation of the improvement, partly in section and as applied. Fig. 3 is a sectional plan view of the same on the line 3 3 of Fig. 2, and Fig. 4 is an enlarged perspective View of the protecting-cap.

To the inner portions of the lenses A of the eyeglasses are secured in the usual manner the studs or posts B, connected with each other by an arched spring 0, and the said posts support the nose clamps or guards D. The free end of the connecting-arm D of each nose-guard D and the corresponding end of the spring C extend in the usual recess in the head B of the corresponding post B, and the said ends are secured in the said recess by a screw E, as plainly shown in Fig. 3.

Now in order-to prevent the screw E from unscrewing and to render the head of the o screw invisible and not liable to come in contact with and rub or scratch the nose of the wearer I provide a cap F, preferably made of metal and approximately U-shaped-that is, having an arched middle portion F, eX- tending over the head B and the head of the screw F.,as plainly indicated in the drawingsand the side arms F of the said cap extend over the front and rear sides of the head B, and the side arms terminate at their corners in lugs F standing at angles to the side arms in an inward direction to engage the back of the head B adjacent to the shank B of the post. Now in applying the cap the side arms F and lugs F lie in the same plane to permit of placing the cap in position on the head B and then the lugs F are bent transversely to engage the head and side of the head B, as above mentioned.

Now by the arrangement described the lugs F hold the .cap F in position on the head B againstsidewise and up-and-down movement, as the lugs reach to the shank B of the post. The side arms F prevent transverse movement of the cap on the head, and the middle portion F is arched to conform approximately to the shape of the adjacent portions of the spring 0 and connecting-arm D of the nose guard or clamp D. Now when the cap is in position on each post B the screw E thereof cannot unscrew, and the said screw is protected by the cap against moisture to prevent it from corroding, and at the same time the head B cannot come in contact with the nose of the wearer and rub or scratch it, as is so frequently the case with eyeglasses as heretofore constructed. Furthermore, the caps F on the posts of the eyeglasses greatly heighten the appearance thereof.

Having thus described my invention, I claim asnew and desire to secure by Letters 0 Patent- 1. In an eyeglass-fitting a post having a recessed head, a spring, a nose-guard and a screw screwing in the said head for securing the ends of the nose-guard and spring in position in the said recess in combination with a U-shaped cap secured to the post and having an arched solid middle portion engaging the outer face of the head of the screw to prevent the screw from unscrewing in the 00 post, as set forth.

2. In an eyeglass-fitting a post having a recessed head, a spring, a nose-guard and a l of the post-head and lugs projecting from screw screwing in the said head for securing the side arms and engaging the back of the the ends of the nose-guard and spring in popost-head, as set forth. sition in the said recess in combination with In testimony whereof I have signed my 5 a cap secured to the post and having a solid name to this specification in the presence of I 5 middle portion engaging the outer face of two subscribing witnesses.
